511rwhp is pretty stout for a 5.4L DOHC 32V V-8 with a Roots-style Eaton blower right from the factory. I think that factory claim of 540 SAE hp is obviously conservative. Even if you use 12% drivetrain loss it still comes out to 580+hp. It makes me wonder what sort of #'s AMG could be putting down with a DOHC 32V 6.3L with a twin screw blower...![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)

I love mustangs. I have owned about 10 already and have another in the works. You never know what they are packing when you run into one on the street, so be careful

I was a Ford store yesterday... I cant get completely into the GT500 in the looks, fit and finish, interior, etc department. I did though, love the exhaust note.
With that being said, the car makes some serious power.

Here is a comment on the edmund board too putting the question to test too...
I have been consistantly putting down 440's to 450 rwhp on dynamics and mustang dynos and top trap is 117.12; that GT 500 weights about the same as the C55 too
60+ rwhp should be indicative of 122-125 traps...
No the GT-R comparisons have an interesting point. Not for the fan boy my car vs your car arguments, but as a techincal question.
Edmunds dyno tested their own GT-R, though admittedly on a different Dyno, and it put down 400ish hp.
Now this GT500 puts down over 100hp more.
Edmunds has also repeatedly tested their GT-R to trap over 118mph in the 1/4 mile.
The last test of the GT500 Edmunds got a 114.7 trap speed. Now yes they did face a headwind, but it is consistant with with other magazines have been getting. Car and Driver for example only traped 113mph with their GT500.
The GT-R and GT500 are of similar weight. The GT500 appears to make alot more power. Yet the GT-R will beat it in trap speed (so launch isn't as much of an issue).
Is this all down to the dual clutch transmission and better gearing? If Edmunds still has access to this GT500, it would be interesting to do some head to head acceleration runs against their own GT-R. Maybe this GT500 actually makes alot more power than the last GT500 they tested.
In the end 511 rwhp, similar weight to a GT-R, and 114.7 mph traps just don't add up right.

The GT500 weighs about 3,900+lbs which I believe is heavier than your C55. You also have to figure in all the little things we do to get an advantage at the track...icing our intakes, taking out all the dead weight from the trunk, running with less than a 1/4 tank of gas (gas weighs 6lbs a gallon) and maybe cooling down the car longer than a bunch of auto journalists trying keep on a schedule.
BTW...a MUstang dyno will normally show much lower hp figures than a Dynojet. Your 440-450rwhp is at least 470-480rwhp on a Dynojet.

The new GT500 is major drool worthy to me, I love it. The interior and fit & finish is much improved over the older models too, but of course, it is still a Mustang, so that's still not anything to write home about.
I used to be a huge Mustang guy and owned some, then my taste in cars changed and the '05's dropped the ball for me. This new Shelby just hits the right spot again though.

The GT500 is a flying brick. where as the GTR is designed to slip through the air like silk. check out the under tray on the GTR and you will see what I am talking about. still the GT500 is a nice car for the money and with the right mods that car is dangerous.

I noticed the high HP numbers and the slow acceleration times too. The latest Road & Track has compared two new convertables:
Ford Shelby GT500 4.6 0-60 and 12.9 at 113.4 mph.
Porsche Boxter S - 4.1 0-60 and 12.6 at 110.2 mph.
What gives?
I hate to say it, but Ford is once again behind the curve. The Horsepower war is over. It's all weight savings and Launch Control systems now. That is the new bar.

I was side by side with a GT500 about a week ago at around 65, was in the lowest gear, and we punched it...dead even up to about 120 when we had to let off due to Mexican traffic...
